About Restoration Window Glass

Restoration Glass® is found in our country's most prestigious restorations, including The White House, Mount Vernon, and Monticello. From its aesthetics to its manufacture and tradition, Restoration Glass® closely reproduces the cylinder antique window glass of the 17th through early 20th centuries. It is the architect and designer's first choice for replacement of broken or missing antique window glass, as well as the detailing of reproduction homes and furniture.

Restoration Glass® is available in two varieties, Full and Light, displaying two levels of "movement" (distortion) to match precisely the desired time period or glass appearance:

Full Restoration Glass® is more distorting and accurately replicates glass made in the 17th and 18th centuries. Its distinct appearance makes it an excellent choice for older colonial-style windows and cabinets, as well as antique and reproduction furniture.

Light Restoration Glass® is less distorting and an excellent match for glass found in structures built in the 19th and early 20th centuries. The slight distortion can be hard to distinguish in a small sample viewed up-close; however, it becomes more pronounced when viewed from a distance, in reflected light, and over a larger area. These characteristics make Light Restoration Glass® ideal for use in windows and doors.

The historic accuracy of Restoration Glass® is due to the careful preservation and practice of authentic, antique mouth-blown glass-making processes by Lamberts' skilled craftsmen. Each sheet of Restoration Glass® is handmade utilizing centuries-old techniques and hand-selected at the factory to ensure the finest quality. The glass exhibits mild surface distortions, an occasional air bubble or pit, and other "imperfections" found only in original mouth-blown and antique window glass types.

Restoration Glass' ease of handling, consistent thickness, and brilliant body make it a preferred alternative to salvaged antique window glass.

Bendheim now offers Restoration Glass® in safety form, laminated to 1/8" (3 mm) window glass, to satisfy the most demanding building safety codes and sound control requirements. Laminated Restoration Glass® meets the requirements for ANSI Z97.1 and the Consumer Product Safety Commission Standard 16 CFR 1201. It is ideal for use in doors, sidelites, windows, and wherever safety is required.

Restoration Glass® can also be incorporated into insulated door and window units (IGUs). Please discuss this option with your window manufacturer.

About Lamberts® Crown Bullion Glass

From its aesthetics to its traditional manufacturing process, Lamberts® Crown Bullion Glass, also known as "bullseye glass," reproduces antique mouth-blown window glass developed as early as the 7th century. The glass features characteristic concentric striations creating subtle, radial distortions, and a bulls-eye center. These authentic crown bullion glass features result from the centuries-old production techniques preserved and practiced by Lamberts' skilled glass blowers.

The process of creating these precious glass pieces begins with a gather of molten glass on the end of a blowpipe that is rhythmically blown, spun, and, as the balloon of glass reaches the desired size, opened outwards like a "crown."' The glass is then transferred from the blowpipe to a solid iron rod, and flattened into a disc by reheating and spinning.

Production of Mouth-Blown Crown Bullion Glass

The unmistakable hand-made quality of Lamberts® Crown Bullion Glass, its authentic production methods, consistency, and delicate beauty make it a refined, historically-accurate choice for the restoration of antique structures, doors, sidelites, transoms, and furniture, as well as a superb decorative glass to accent traditional and contemporary windows, glass partitions, and cabinets.

Lamberts® Crown Bullion decorative mouth-blown glass pieces are available in three sizes - approximately 8" x 8" (20.3 cm x 20.3 cm), 10" x 10" (25.5 cm x 25.5 cm), and 12" x 12" (30.5 cm x 30.5 cm). Custom sizes are available on request. Please e-mail us your requirements: info@bendheim.com

The History of Bendheim and Lamberts Glass

Restoration Glass® and Crown Bullion (Bullseye) Glass are brought to you through the decades long collaboration between Bendheim and Glasshutte Lamberts of Germany. In 1979, Bendheim recognized the need for glass suitable for serious historic restoration and reproduction work. Bendheim chose our life-long partner, Lamberts, known internationally as the finest producer of traditional, blown sheet glass, to reproduce these glass varieties. The result: superior, authentic mouth-blown restoration window glass that no machine-made glass can compare to.

Since then, Restoration Glass® has become an important part of some of America's most distinguished historic restorations, including the White House, Mount Vernon, and Monticello. When you purchase Bendheim Restoration Glass®, you receive the finest glass for historic restorations and reproductions in the world.
